传输错连对交换系统的影响与预防研究

Research of Impact of Transmission Misconnection on Switching System and Prevention Measures

SDH传输系统自身的保护机制和时隙复用原理决定了其承载的业务可能会产生错连,在传输与交换共同组网的环境里,错连可能对交换系统造成重大影响。通过对传输、交换典型组网中错连问题的研究,提出了错连的预防措施与网络优化方法,为通信行业技术人员提供借鉴。

Due to its own protection mechanism and the principle of time slot reuse, it is doomed that the services over a SDH transmission system may generate misconnections. In an environment of combining transmission and switching, a misconnection may severely affect the switching system. By studying misconnections in typical transmission and switching network, measures for prevent misconnections and optimization approach are given, providing reference for communication professionals.
